The Sand Martin is very sociable in its nesting habits; as many as a hundred pairs will nest close together. The nest is a litter of straw and feathers in a chamber at the end of a 4-foot burrow. With so many roommates, it often becomes a hotbed of parasites. *Looks around in relief to empty apartment* 😅 . . #wildlife #animals #videooftheday #birds #nests #animalhomes #nesting #waterbird #bird #smallbird #birdsofinstagram #mallardduck #birdwatching #birdphotography
